Fist of the North Star: Lost Paradise is a crossover between post-apocalyptic manga classic Fist of the North Star and Sega’s action-adventure series about the Japanese underworld, Yakuza. If that previous sentence made no sense to you, the barrier to entry may be high; but fans of either series will find something to enjoy.
Spin-offs included, more than a dozen games have been released in the Yakuza series since the first entry back in 2005. There may have been zombies and samurai, but the Fist of the North Star crossover is the first game in the series set in a completely fictional world.
Like in the original manga by Buronson and Tetsuo Hara, the game follows the story of Kenshiro, the successor of a deadly martial art called Hokuto Shinken. After a nuclear war during the end of the Twentieth Century, the world has become a hopeless wasteland. Survivors are few, and the only law that counts is that the weak are victims of the strong.
